Petrus Bonus Lombardus was a supposed fourteenth century physician at Ferrara, and writer on alchemy. He is best known for the attribution to him of Margarita preciosa novella, from around 1330, an influential alchemical text. His supposed Introductio In Divinam Chemicae Artem was much later printed (1572).
